Abstract (en)

A clathrate between cyclodextrin (CD) and drospirenone (DRSP) was prepared and used in pharmaceutical compositions. By the method in which the CD-DRSP clathrate was prepared, inclusion complexes between beta - cyclodextrin and DRSP of at least 1:1, 2:1 and 1:2 were made available. As part of an inclusion complex, drospirenone has an increased water solubility, which is advantageous for its use as a medicament for the treatment of menopausal symptoms and for female contraception.
